CORNER-IRON FOR CHAIRS.

SPECIFICATION forming part of Letters Patent No. 323,117, dated July 28,1885.

Application filed May 15, 1884.

To all whom it may concern.-

Be it known that we, ISAAC D. OoMs'rocK and EDWARD J. GIBSON, of Adrian,in the county of Lenawee and State of Michigan, have invented new anduseful Improvements in Corner-Irons for Chairs; and we do hereby declarethat the following is a full, clear, and exact description thereof,reference being had to the accompanying drawings, which form apart ofthis specification.

This invention relates to certain new and useful improvements incorner-irons for knockdown chairs.

The invention consists in the peculiar construction of a corner-ironadapted to be secured upon the ends of rails of the seat and to engagethe posts of the chair-frame, so that when the chair is set up the partswill be held securely together, all as more fully hereinafter set forth.

Figure 1 is aperspective view of a chairframe provided with our improvedcorneriron. Fig. 2 is aplan of a chair-seat provided with our device ateach corner. Fig. 3 isa perspective of the corner-iron detached.

In the accompanying drawings, which form a part of this specification, Arepresents a section of one of the front legs or part of a chair; B, theside rail, and O the front rail, of the seat.

D represents. one corner-iron, preferably constructed of malleable iron,provided with the two sockets a a for the reception of the ends of therails. These sockets a may be of any desired shape; or they may be openat one side, into which a dovetail tenon in the end of the rail may beinserted, or in any other manner by means of which the iron can be (Nomodel.)

rigidly secured to the rails. Upon that portion of the iron that issecured to the side rail, B, there is cast a tenon, b,which fits into acorrespondingly-shaped hole bored in the chair leg or post to receiveit. The face 'of the iron from which the tenon 1) projects is designedto conform to the shape of the leg upon which it is to be employed,

In practice, a corner-iron such as is herein described is rigidlysecured to the rails of the seat at the junction of the seat-rails,(Fig. 2,) and the chair can be packed for transportation in compactknockdown form. When it is desired to set up the chair, the sidespreaders are inserted in the back posts or legs and the rear side ofthe seat-frame placed in position, the tenons b entering the holes inthe legs provided for them; the front leg-frame is then likewise put inproper engagement with the Spreaders and seat-frame. To secure the partstogether, a lip, c, in the iron may be driven into the adjacent leg, ora screw may pass through such lip into the leg.

What we claim as our invention is l. A chair corner-iron, D, having theface which fits the chair-leg provided with a tenon, b, and the oppositeface provided with the arms a a, substantially as specified.

2. A corner-iron for chairs, consisting of the iron D, provided with thetenon b, lip o,

and arms a, when constructed substantially in the manner and for thepurposes specitieoh ISAAC D. COMSIOOK. EDWARD J. GIBSON.
